JAMES L. PERRY, OF MANSFIELD, AND MELZER BURT, OF NORTON, MASSACHUSETTS.

FLUID-MEASURER.

Specification of Letters Patent No. 23,701, dated April 19, 1859.

To all whom it may concern:

Be it known that we, JAMES L. PERRY, of Mansfield, and MELZER BURT, of Norton, in the county of Bristol and State of Massachusetts, have invented a new and useful F luid-Measurer or Apparatus for Measuring the Flowage of a Liquid from a Cask or Reservoir; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, is a top view. Fig. 2, a side elevation, and Fig. 3, a vertical and central section of the same.

The object of our invention or fluid measurer is to enable a person to draw from a cask or reservoir and discharge into a receiving vessel a determined quantity of fluid or some proportional part thereof, and to accomplish this simply by opening and closing certain faucets.

In the drawings, A, denotes a measuring cistern or vessel of cylindrical form, the same being constructed with a valve opening, a, on the top and with a float valve, Z), applied to such opening so as to close the same by hydrostatic pressure, when the vessel is full of fluid. Surrounding the valve opening is a tunnel or curb, 0, furnished with a hinged cover, d, the same being not only to catch and retain any liquid which may accidentally escape through the valve opening but to cause it to pass back into the vessel, A, whenever the valve may fall away from the opening. The said Vessel, A, is to be provided with an induction faucet, B, by which it may be attached to a cask or reservoir from which it may be desirable to remove a liquid. Furthermore, such vessel, A, is not only to have aneduction faucet, O, placed at its bottom, but sundry other eduction faucets D, E, which may be arranged at such heights above the bottom of the vessel as to indicate the measure of fluid to be drawn from the vessel. For instance, if the vessel when full will hold exactly one gallon of fluid, the faucet, D, if placed at half the height of the vessel, will, after being opened (provided the faucet, B, be rst closed) draw out of the vessel just half its contents or one half a gallon. So with regard to the faucet, E, if it be situated at three fourths the height of the vessel above the bottom thereof it will, on being opened, discharge from the vessel one quarter of a gallon.

The discharging faucets are not arranged directly over one another, but aside from one another so that a stream from either may not fall on any one below it such arrangement being as shown in the drawings.

By means of our invention' much leakage or waste of fluid may be prevented in reference to the common gallon or other measures in use as ordinarily employed.

lVhen our fluid measurer is applied to a Cask and it may be desirable to extract from the measurer, A, either the whole or a given portion of its contents, the induction faucetshould first be opened and the fluid suffered to run into the vessel, A, until itl may be filled, which will be known by the closing of the tell-tale valve above described. Next the induction faucet should be closed and that eduction faucet opened which will draw off the amount of fluid that may be required. As soon as the draft commences the valve will open by the pressure of the atmosphere and thereby enable the fluid to flow easily out of the faucet.

If each of the eduction faucets be eX- tended into the vessel to its vertical axis, such faucet will draw its proper quantity from the vessel however the latter may be inclined from the horizontal plane.

7e claim- The fluid measurer, constructed substantially in manner and to operate with respect to a barrel or reservoir as specified, that is to say, as made of a close vessel, A, induction and eduction faucets and a tell tale valve and valve opening or equivalent, combined and arranged essentially as set forth, the valve serving to indicate when the case may be full of liquid, the induction faucet allowing the flowage and interruption thereof of liquid into the case, and the eduction faucets determining the amount of flowage out of the case as described.

In testimony whereof we have hereunto set our signatures.

JAMES L. PERRY.

MELZER BURT.
